SPECIFICATION forming part ofLeaersratene No. 712,45`asated october 28, 1902. Application iiled July 28, 19Q2. Serial No. 117.405. (No model.)

To @ZZ whom it may con/carni Be it known that I, EDWARD ML I-IEYLMAN, of the city of Janesville, county of Rock, and State of Wisconsin,have invented certain new and useful Improvements in Corn-Planters,

` of which the following is a specification.

This invention relates toplanters in which the dropping mechanism is actuated or conltrolled by meansof a knotted Wire which runs lo through guide-pulleys in the check-row heads of the planter; and the object `is to provide means for releasing the Wire from the planter by the act of raising the front frame to get the furrow-openers clear of the soil. l The invention is exemplified in the structure hereinafter described, and it is denedin the appendedclai'ms. A i Corn-planters are made with two frames, a rear wheelframe on which the' driversits and 2o a front frame which is provided with furrow-` openers and seed-dropping mechanism. The

front end of the rear frame is hinged to the front frame, and in raising and lowering the front frame the rear frame rocks wit-h the axlez 5 shaft for a pivot and changes its relation to the horizontal. The front frame rises and falls without materially changing its relation to the horizontal, and so the angle formed between the two frames changes as the front 3o frame rises and falls.

Itis common to provide planters with checkrow heads having guide-pulleys for the wire, and the heads are each made in two parts hinged together and secured in an operative 3 5 position by means of a releasable catch. The swingable part of the head is -pivoted outside the fixed part. The pivots are below the guide-pulleys of the head, and they extend lengthwise of the head and parallel to the line 4o of travel of the planter. The Wire pulls outward on the guide-pulleysI of the check-row head, particularly as an end of the eld is neared.` 'The 'pulltends to separate the two parts of the head, and whenever the catch that 4 5 secures the two part-s together is released the Wire at once tilts the swingable part outward and detaches itself from `the planter. Heretofre it has-been customary to release the catch by pulling on aline extending from the 5o catch to near the seat of the driver; but this requires an operation separate from the raising of the front frame of the planter. The furrow-openers must be raised and the checkrow wire must be thrown off before starting to turn the planter around, and the present invention provides means for performing the two operations simultaneously.

In the drawings forming part of this speciiication, `Ffigure 1 is a plan of so much of a planter as is needed to explain my invention. Fig. 2 is a diagram in side elevation, showing how motion is obtained from the rise of the front frame to release the catch that holds the two parts of .the check-row' head together. Fig. 3 is an end viewofa check-row head, showing the swingable part released and swung outward to throw off the wire;

A covering-wheel is shown at 1, and a part of the axle-shaft is shown at 2. A side bar 'of the rear frame of the planter is shown at 3.

A bracket 4 is secured to the cross-bars 6 and 7 of the front frame of the planter, and the bar 3 of the rear frame is connected pivotally with the bracket at 5. The tongue 8 is secured to the front frame,iand `it holds such frame against material horizontal change during its rise and fall. A seedbox is shown at 9. Brackets 10 and ll'are secured to the rear cross-bar 7 of the front frame, and they project rearward therefrom. A rod12 has rocking bearings in brackets 10 and 11, and its ends 13 and 15 are cranked, one upward and backward and the other upward and forward. A bend 14 is formed on the termination of crank 13, and such bend extends beneath bar 3. The xed part 17 of the check-row head is attached to cross-bars 6 and 7, and the part 18 is pivotally connected with the fixed part, as shown at 27 in Fig. 3. 'The two parts of the check-row head are held together bya releasable catch19. A spring-2O tends to hold the catch in an engaging position, and a link 16 connects a swinging end of the catch with the cranked arm of rod 12'.l The pulleys for the xed part of the head are shown at 21. The pulleys for the swingable part of the head are shown at 22. Acheck-row shaft S23-has a forked lever 24, through which wire 26runs, and the forked lever is hinged to swing with the swingable part of the check-row head When the wire is thrown off. A drill-shaft is shown at`25. The rod 12 is somewhat elastic;

IOO

but its torsionalstrength is sufficient to transmit force from crank 13 to crank 15 and pull the catch 19 from engagement with the part 18 of the check-row head. So long as the furrow-formers are in the soilthe end 14 of crank 13 is out of contact with frame-bar 3, as shown lin solid lines in Fig. 2; but as the front frame approaches its highest position the crank-arm 13 engages bar 3 and the completion of the rise of the planter depresses crank 13, pulls backward on crank 15, and forces the catch 19 from engagement with part 18 of the checkrow head. (See broken lines-in Fig. 2.) If the upward motion of the front frame should4 be greater than is required to release thel catch, the torsional elasticity of rod 12 will avoid breakage or detrimental strain of the parts. As soon as the front frame is low-l ered the spring 2O will swing catch 19 into position to engage part 18 of the check-rowv head, when such part is returned to its oper-g ative position.

I claim- 1. In a planter, the combination cfa front frame carrying planting mechanism, a frame supportedlon wheels and hinged at its frontI endto the front frame, a tiltable wire-guide4 onthe front frame, a catch to hold the tilt- Aable wire-guide in operative position and a` releasingappliance for the catch mountedon the front frame andactuated by the swing of the rear frame.

2. In a planter, the combination of a front frame carrying planting mechanism, a frame vsupported on wheels and-hinged at its front end to the front frame, a tiltable wire-guide on the front frame, a catch to hold the tilt-` able Wire-'guide in operative position, a rockshaft journaled in the front frame, an arm 0fthe rock-shaft extended under a bar of the rear frame in the rear of the hinged conjunction of the frames, and a connection between the rock-shaft and the catch, whereby the catch is released by pressure derived from the rear frame as the front frame is raised.

3. .In a'planter, the combination of afront frame carrying planting mechanism, a frame supported on Wheels and hinged at its front end to the front frame, a tiltable wire-guide on the .front frame, a catch to hold the tiltable Wire-guide in operative position, a rockshaft journaled in the front frame, an arm on the rock-shaft extended under a bar of the .frame carryingplanting mechanism,aframe supported on Wheelsand .hingedatlits front endto the -front frame, atiltable wire-guide on the front frame,.a catch .to hold .the tiltable wire-,guide in operative position, an elas- `tic rod journaledin the frontframeandhavfingone endcranked yupward and y.rearward -while theother end is cranked upward and forwarda bar ofthe .rear `frame Vextending above the rearward extension ofthe rod, and a link connecting .the forward .extension of .the rod with the catch .for kthe ltiltable `wireguide.

In testimony whereof Isign my name in the presence of two subscribing witnesses.
